Sofi didn't pay off my entire student loan balance leaving me with over $1,200 to pay outside of my new refinanced loan with Sofi. They claimed they based the payoff amount on the statement I provided, however the statement I provided clearly stated the outstanding balance and outstanding accrued interest balance. They shorted the loan and gave me unsatisfactory options to correct the issue. I would caution anyone trying to refinance their student loans through Sofi.
